start&stop rtl_433 inside container

[mosiser]

As a Docker newbie user, I'm trying to apply this command
while true; do rtl_433 -R 32 -f 868300000 -Y classic -s 250k -E quit; sleep 44; done
discussed here merbanan/rtl_433#3347
to the container.

So, if I understand correctly, since "while" needs to run before rtl_433, I need to override the container's ENTRYPOINT...

After some hard work 😅, I came up with this setup:

  rtl433:
    container_name: rtl_433
    image: hertzg/rtl_433:latest
    entrypoint: ["/bin/sh", "-c"]
    devices:
      - "/dev/bus/usb/001/003"
    command: ["while true; do rtl_433 -R 32 -f 868300000 -Y classic -s 250k -E quit; sleep 44; done"]
    restart: always

which seems to work!

Is it correct, or am I doing something wrong? Any suggestions?

Thanks for any help.

Is it correct?

Since it does what you want and you say that it works for you then it's correct. 😁

Am I doing something wrong?

Depends who you ask, but if you want to automatically restart on exit. or "crash", The restart: always does that for you, you don't need to do all that stuff.

If you are talking about having a 44 second delay between restarts, theres probably something else that's wrong that's forcing you to do such hacks

Any suggestions?

Assuming you are doing homelab, as long as it works for you keep at at.

On the other hand Containers are not VMs and do not treat them like such but that's out side of the scope of this project.
